Fail to add Search Engine to right click menu

[TickTack]

I want to add baidu search engine to my primary search engines that can appear in the right click menu, but still keep Google as my default search engine. However, once I default baidu then default google, baidu disappears from default search engines/right click menu and appears in other search engines. I guess the previous version doesn't have such bug/feature? Can you kindly fix this? 

Thanks

This is a Chromium feature. Manually added search engine can stay in "Other search engines" only.
